It is further advised that the records be reviewed by the electroencephalographer with the EEG technologist present. This is very helpful when problem areas contained in the EEG are called into question. Also, new ideas can be acquired for the next neonatal EEG procedure with the joint reading...
Procedure Electroencephalography, or EEG, is an electrophysiological technique commonly used by researchers studying cognition. The brain constantly generates electrical activity, which can occur spontaneously, or when induced by stimulation. EEG is a noninvasive, portable and inexpensive technique that can...

Merriam-Webster defines an algorithm asa step-by-step procedure for solving a problem or accomplishing some end. Algorithms can be developed for any process—from how to make your morning coffee to something as odd as establishing a friendship (diagram). In the biosensor world, you will hear p...
the speller application determines the final target row and column with the highest scores among the 6 row and column sequences. Finally, a single letter is printed and begins the next block. Figure3brepresents the P300 speller task procedure for a single word block, and step by step explanati...
1, the procedure can be divided into data pre-processing, feature extraction, training, testing, and post-processing. The raw EEG data were pre-processed and segmented into non-overlapping 5-second windows to extract relevant features. Then, the data were divided into two groups: the training ...
2.3. Procedure and experimental design The stimuli detailed above were used in a lexical decision task (LD) and a semantic decision (SD) task. Participants sat in a comfortable chair located in a dimly lit and sound-attenuated magnetically shielded room. The experiment was implemented with e-Pri...
The next step involved computation of the average or grand mean microstate maps of the healthy elderly group (n = 308). The four healthy grand mean maps were then assigned as class A–D based on the similarity to the maps from the normative study. Following the same sorting procedure, the...
We also point out a subtle difference. In the field of EEG signal analysis, the termepochis used. EEG epoching is a procedure in which specific time-windows are extracted from the continuous EEG signal. In our approach we use the term window and not the epoch to emphasize a slightly diffe...
As BioSemi is a “reference free” acquisition system, the Common-Mode (CM) voltage is recorded in all channels, thus a re-reference step is needed. This procedure was made by means of the specific MNE re-reference function, using channels EXG1 and EXG2. The aforementioned function creates...
